The 3W525 is a low profile balanced to unbalanced transformer
designed for push-pull amplifiers in an easy to use surface
mount package for PCS, DCS, . These compact Xinger® surface
mount baluns are ideal for high volume manufacturing and are
more reliable and repeatable than traditional baluns. The
3W525 has an unbalanced port impedance of 50⦠and
balanced port impedances of 25⦠to ground with a 50⦠balance
between outputs. This eases the matching of the push-pull
amplifierâs power transistors, which have low impedance levels.
The output ports have equal amplitude (-3dB) with 180 degree
phase differential. The Xinger® balun is a res ult of years of
research and development culminating with a solution so
unique, a patent is pending on the design approach. The 3W525
is available on tape and reel for pick and place high volume
manufacturing.
